The Reporting Person hereby grants to each such attorney-in-fact full power and authority to do
and perform any and every act and thing whatsoever requisite, necessary, or proper to be done in

not assuming, nor is the Trust assuming, any of the Reporting Person's responsibilities to comply
with Section 16 of the Securities Exchange Act of 1934.

This Power of Attorney shall remain in full force and effect until the Reporting Person is no
longer required to file Forms 3, 4 and 5 with respect to the Reporting Person's holdings of and
transactions in securities issued to the Trust, unless earlier revoked by the Reporting Person in a
signed writing delivered to the foregoing attorneys-in-fact.

IN WITNESS WHEREOF, the Reporting Person has caused this Power of Attorney to be
